Publisher's Announcement s 



In May, 1915, the first edition of "Smith's Butterfat Com- 
puter" was published to meet the demands cf buyers of 
cream, milk, butter, eggs and poultry. It soon met with a 
hearty reception by thousands of men who had been look- 
ing for just such a set of tables. In almost every small 
town in the United States there are from one to several 
buyers of cream and milk for the central creameries. As 
soon as these agents learned of the Computer they at once 
ordered. Many of the large central creameries purchased 
the books by the hundred to be furnished to their agents. 

Hundreds of letters have been received commending the 
book for its handy arrangement, its large clear type and its 
accuracy and easy application. 

These tables have been used in almost every kind of bus- 
iness where multiplications were made, including pay roll 
departments of large factories. They are especially useful 
where employees are paid by the hour or piece. 

My former offer was to send a free copy to any person 
finding an error in the tables. The same offer is made rel- 
ative to this edition, if the error amounts to 1 cent in the 
result. 

The unusually high price now paid for butterfat has 
made the demand for a larger book with the tables running 
to 99 with the half fractions running on every page. This 
demand has been fully met with this edition. 

The cost of this edition is more than double that of the 
former editions. It is also larger, better bound in every way 
and a much better book. The price of the book has been 
increased from $1.50 to $2.00. With the increased cost in all 
lines of printed books and blanks this small additional cost 
will not be objectionable. 

Since publishing the former edition I have moved my 
home and publishing business to Kansas City. Mo., U. S. A., 
where the facilities for distributing are much better than 
at Pleasanton, Ivans., my former home. 

Thanking my thousands of friends for their generous 
endorsements of my Computers and hoping this new edition 
will meet all of the demands of the present high prices of 
all commodities where it is applied. 

I am very respectfully, 

J. FRANK SMITH, Publisher. 
Kansas City, Mo., U. S. A. 



HOW TO APPLY THE TABLES. 

The success of the tables in this computer depends on 
the operator, and to get quick results, one should know how 
to apply them to the best advantage. The tables are sim- 
ple and easy to understand and are capable of a wide range 
of application. Here are a few rules and suggestions that 
will enable one not familiar with them to apply the tables. 

TO FIND BUTTERFAT IN CREAM. 

The tables have a wide range for tests of cream, includ- 
ing all tests from 5 per cent to 99 per cent with the half 
fraction in each table. To find the fat in any lot of cream, 
use the table representing the test and run to the number 
representing the number of pounds and the number opposite 
is the pounds of fat. Example: 25 lbs. cream test 27 per 
cent. Use the 27 table and run to 25 and you have 6.75 lbs. 
fat. 

TO FIND FAT IN WHOLE MILK. 

The tables include the tests of whole milk from 1.5 per 
cent to 9.9 per cent with all the tenths. To get the fat in any 
lot of milk, use the table representing the test and run to 
the number of pounds. Example: 76 lbs. milk test 3.4 per 
cent. Use the 34 table and run to 76 and you have 25.84, 
but since the test is 3.4 per cent in place of 34 per cent the 
decimal should be moved one place to the left and it leaves 
2.5S lbs. fat. 

TO FIND VALUE OF FAT AT ANY PRICE. 

The tables mav be transposed any way and the correct 
results obtained. Example: 34 lbs. fat at 25 cts. per lb. Use 
the 34 table and run to 25. or use the 25 table and run to 34. 
Another example, 34 1-2 lbs. fat at 25 cts. per lb. Use the 
34 1-2 table and run to 25. Example: 34 lbs. fat at 25 1-2 
cts. per lb. Use the 25 1-2 table and run to 34. Example: 
9.S lbs. fat at 25 cts. per lb. Use the 25 table and run to 9S 
and move the decimal one place to the left. Example: 45.S 
lbs. fat at 25 1-2 cts. per lb. Use the 25 1-2 table and run 
to 45 and you have the value of the 45 lbs. Then run to 8 
and move the decimal one place to the left and add to value 
of 45 lbs. 

TO FIND VALUE OF BUTTER. 
Apply the tables the same as butterfat. 



TO FIND FAT IN MORE THAN 100 LBS. OF CREAM OR 
MILK. 

un to 100 It la well to know how 

to compute tli.' fai In more than 100 lbB. of cro.im or milk 

in 150 pounds of cream or milk DM

to the number representing the number of dosen.

i iblc and run to 11 and yon have 

.1 to >;>•( the value of 7 eggs run to El anil you have 

ad when once used will be 

very handy. 



TO FIND VALUE OF POULTRY. 

Apply the tables the same as in finding value of butter 
or butterfat. 



FOR WAGE TABLES. 

When factories, etc., pay emplo yees by the hour or the 

• tables can be used successfully. Example: -13 hours 
at 17 1-2 cts. per hour. Turn to 47 1-2 table and run down 
first column to 43 anil you have $20.42".. Example: 17 1-1 
hours at 43 cts. per hour. Use the same tables in same 
way. Example: 17 1-2 hours at 43 1-2 cts. (.435 cts.) per 
hour. Use 17 1-2 table and run to 43 and you have $20,425. 
Then on same table run to G and you have 2.375; but the 
5 Is only .5 so you shift the decimal one place to left and 
have 1.2375; then add this to the first amount and you have 
10.66 i 1 i seem a little slow at first but after a 
little practice it will be very easy, if paying by the piece 
the tables will compute any number to 100 and at any price 
per piece or dozen by half cent up to 99 1-2. 

HOW TO FIND FRACTIONAL PARTS. 

If it Is desired to find fractional values in any table. 

d thus: 49 3-4 pounds butterfat at II 1-2 

,-ts. ]„■!■ pound: Tutu to It 1-2 page or table and run to 49 

i ■ have $23.52. To find the value of 3-4 pounds Just 

r ii .75 pound and run to 75 in the 48 1-2 table and you 

have 16.375, but by moving the decimal to its proper place 

equal $23. SS. value 
i lbs. fat at 48 1-2 cts. If the fractional part Is 1-4 
In the table as it will represent .25. If you have 1-2 
mi to represent .5. 

TO FIND DECIMAL PARTS. 

If you have 19.1 pounds of fat at II 1-2 ets. per pound, 

I find the value of the .8 i>ound by noting the 

number 1 In the 11 1-2 table and mov- 

mal. Example: 19. 1 pounds fat, price 48 1-2 

and find 49 and yon have 

Then by referring to s you have 3.88. but the de- 

to the left, making $ .388. 

i : This same 

i, find the value of any decimal part of a pound on

Here is a rule to compute value of less than dozen egirs 
at any price. 1 egg, (1-12 doz.) equals .OS of a dozen; 2 eggs, 
(1-6 doz ) equals .17; 3, (1-4 doz.) equals .25; 4, (1-3) equals 
.33; G. (5-12) equals 42; 6, (1-2) equals .50; 7, (7-12) equals 
.68; 8. (2-3) equals .67; 9, (3-4) equals .75; 10, (5-6) equals 
.88; 11, (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

(1-6 di ! : doz.) equals .25; 4. (1-3) equals 

12; c, (1-2) equals .60; 7. (7-12) equals 

equals .67; 9, (3-4) equals .76; 10. (5-6) equals 

(11-12) equals .92. Under the table representing the

Here la a rule to compute value of less than dozen eggs 
at any price. 1 ere. (1-12 doz.) equals .08 of a dozen; 2 eggs, 
(1-6 doz.) equals .17; 3, (1-4 doz.) equals .25; 4. (l-.Ti 
.33; 5. (5-12) equals .42; 6, (1-2) equals .50; 7. (7-12) equals 
.63; 8, (2-3) equals .67; 9, (3-4) equals .75: 10, (5-6) equals 
.83; 11, (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here Is a rule to compute value of less than dozen eggs 
at any price. 1 egg, (1-12 dor.) equals .08 of a dozen; 2 eggs, 
(1-6 doz.) equals .17; 3. (1-4 doz.) equals .26; 4, (1-3) equals 
.33; 5, (5-12) equals .42; 6, (1-2) equals .50; 7. (7-12) equals 
.58; 8, (2-3) equals .67; 9, (3-4) equals .75; 10, (5-6) equals 
.S3; 11, (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here is a rule to compute value of less than dozen eggs 
at any price. 1 egg. (1-12 doz.) equals .OS of a dozen; 2 eggs, 
(1-C doz.) equals .17; 3. (1-4 doz.) equals .25; 4, (1-3) equals 
.33; 5. (5-12) equals .41'; 6, (1-2) equals .50; 7, (7-12) equals 
iL'-3) equals .67; 9. (3-4) equals .75; 10, (5-6) equals 
.83; 11, (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here is a rule to compute value of less than dozen eggs 
at any price. 1 egg. (1-12 doz.) equals .08 of a dozen; 2 eggs, 
(1-6 doz.) equals .17; 3, (1-4 doz.) equals .25; 4, (1-3) equals 
.33; 5, (5-12) equals .42; 6, (1-2) equals .50; 7, (7-12) equals 
.58; 8, (2-3) equals .67; 9, (3-4) equals .75; 10, (5-6) equals 
.S3: 11, (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here is a rule to compute value of less than dozen eggs 
at any price. 1 egg. (1-12 doz.) equals .08 of a dozen; 2 eggs, 
(1-6 doz.) equals .17; 3. (1-4 doz.) equals .25; 4, (1-3) equals 
.33; 6, (5-12) equals .42; 6, (1-2) equals .50; 7. (7-12) equals 
.68; 8, (2-3) equals .67; 9. (3-4) equals .75; 10. (5-6) equals 
.83; 11, (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here Is a rule to compute value of less than dozen eggs 
at any price. 1 egg, (1-12 doz ) equals .08 of a dozen; 2 eggs, 
(1-6 doz.) equals .17; 3, (1-4 doz.) equals .25; 4, (1-3) equals 
.33; 6, (5-12) equals .42; 6, (1-2) equals .50; 7. (7-12) equals 
.68; 8, (2-3) equals .67: 9. (3-4) equals .75; 10, (6-6) equals 
.83; 11, (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here Is a rule to compute value of less than dozen epgs 
at any price. 1 egg, (1-12 doz.) equals .08 of a dozen; 2 eggs, 
(1-6 doz.) equals .17; 3, (1-4 doz.) equals .25: 4, (1-3) equals 
.33; 6. (5-12) equals .42; 6. (1-2) equals .60; 7. (7-12) equals 
.58; 8. (2-3) equals .67; 9, (3-4) equals .75; 10. (5-6) equals 
.83; 11, (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here Is a rule to compute value of less than dozen eggs 
at any price. 1 egg. (1-12 doz.) equals .08 of a dozen: 2 eggs, 
(1-6 doz.) equals .17; 3, (1-4 doz.) equals .25; 4, (1-3) equals 
.33; 5, (5-12) equals .42; 6. (1-2) equals .50; 7. (7-12) equals 
.68; 8, (2-3) equals .67: 9, (3-4) equals .75; 10, (5-6) equals 
.83; 11, (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here Is a rule to compute value of less than dozen eggs 
:it anv price. 1 egg, (1-12 doz.) equals .08 of a dozen; L' tm 
(1-6 doz.) equals .17; 3, (1-4 doz.) equals .25; 4, (1-3) equals 
(6-12) equals .42; 6, (1-2) equals .50; 7. (7-12) equals 
.58; 8, (2-8) equals .67; 9. (3-4) equals .76; 10. (5-6) equals 
(ill-) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here is a rule to compute value of less than dozen eggs 
at any price. 1 egg, (1-12 doz.) equals .OS of a dozen; 2 eggs, 
(1-6 doz.) equals .17; 3. (1-4 doz.) equals .25; 4. (1-3) equals 
.33- G, (G-12) equals .42; 6, (1-2) equals .50; 7. (7-12) equals 
5S; 8, (2-3) equals .67; 9, (3-4) equals .75; 10. (5-6) equals 
.83; 11. (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here is a rule to compute value of less than dozen eggs 
at any price. 1 egg. (1-12 doz.) equals .08 of a dozen: 2 eggs, 
(l-f> doz. ) equals .17: 3, (1-4 doz.) equals .25; 4. (1-3) equals 
i 12; 6. (1-2) equals .60; 7. (7-12) equals 
:.s: 8, (2-8) equals .07: P. (8-4) equals .76; 10. (5-6) equals 
88; ii. m-12) equate .91 Cinder the table representing the 
per dozen of eggs, vise these numbers as decimals and 
you will always get correct value of odd eggs.

Here Is a rule to compute value of less than dozen eggs 
at any price. 1 egg. (1-12 doz.) equals .08 of a dozen: 2 eggs. 
(1-6 doz.) equals .17; 3, (1-4 doz.) equals .25: 4. (1-3) equals 
.33; 6, (5-12) equals .42; 6. (1-2) equals .50; 7. (7-12) equals 
.58; 8, (2-3) equals .67: 9, (3-4) equals .75: 10. (5-6) equals 
.83; 11. (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here is a rule to compute value of less than dozen eggs 
at any price. 1 egg, (1-12 doz.) equals .OS of a dozen; 2 eggs, 
(1-6 doz.) equals .17; 3. (1-4 doz.) equals ,26; I, (1-3) equals 
.33; 5. (5-12) equals .42; 6, (1-2) equals .60; 7. (7-12) equals 
.68; 8. (2-3) equals .67; 9, (3-4) equals .76; 10. (5-6) equals 
,88; 11. (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here is a rule to compute value of less than dozen eggs 
at any price. 1 egg. (1-12 doz.) equals .08 of a dozen; 2 eggs, 
(1-6 doz.) equals .17; 3. (1-4 doz.) equals .25; 4. (1-3) equals 
.33; 5, (5-12) equals .42; 6. (1-2) equals .50; 7. (7-12) equals 
.58- 8, (2-3) equals .67; 9, (3-4) equals .75; 10. (5-6) equals 
.83; 11, (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.

Here ia a rule to compute value of less than dozen eggs 
at any price. 1 egg, (1-12 doz.) equals .08 of a dozen; 2 eggs. 
(1-6 doz.) equals .17; 3. (1-4 doz.) equals .25; 4, (1-3) equals 
.33; 5, (5-12) equals .42; 6. (1-2) equals .50; 7. (7-12) equ&ll 
.58; 8. (2-3) equals .67; 9, (3-4) equals .75; 10. (5-6) equals 
.83; 11. (11-12) equals .92. Under the table representing the 
price per dozen of eggs, use these numbers as decimals and 
you will always get correct value of odd eggs.
